[0034] Example

[0035] See also Figure 1-Figure 2As shown, the purpose of this embodiment is to provide a roller conveying device for an edge banding machine, including a conveying roller frame 1 connected to the edge banding machine, a conveying roller group 11 is rotatably installed inside the conveying roller frame 1, a driving assembly 12 for providing power to the conveying roller group 11 is installed outside the conveying roller frame 1, the conveying roller group 11 is used to adjust the position of the plate so that the plate is transported sideways, a fixed frame 2 is installed on the top of one side of the conveying roller frame 1, a conveying wheel 21 is rotatably installed inside the fixed frame 2, the conveying wheel 21 is used to adjust the conveying position of the plate so that the plate is accurately transported into the edge banding machine, and a pressing assembly 3 is installed on the top of the fixed frame 2, and the pressing assembly 3 is used to press the top of the plate for conveying. A leak hole is opened on the side of the fixed frame 2, and the conveying wheel 21 extends to the outside of the fixed frame 2 through the leak hole to adjust the plate on the conveying roller group 11.

[0036] The conveying roller group 11 is rotatably installed inside the conveying roller frame 1, and the driving motor of the driving component 12 is used to connect the conveying roller group 11 through the crawler. When the driving component 12 is started, the plate can be driven to be conveyed on the top of the conveying roller group 11, and a conical roller is arranged in the conveying roller group 11. The conical roller can guide the transmission direction of the plate by its special shape, so that the transmitted plate is offset to the thinner end of the conical roller, and the plate is conveyed sideways, so that one side of the plate can contact the conveying wheel 21 installed on one side of the conveying roller frame 1. The plate is conveyed and moved by the conveying roller group 11, so that the side of the plate rubs against the wheel, so that the conveying roller can adjust the limit of one side of the plate, ensuring that the plate is accurately connected to the inside of the edge banding machine for edge banding, and the conveying wheel 21 can clean dust on the side of the plate that needs edge banding.

[0037] A support plate 4 is fixedly installed on the other side of the conveying roller frame 1, an adjusting plate 41 is installed on the top of the support plate 4, a moving component 42 for moving the adjusting plate 41 is arranged on the top of the support plate 4, a rotating shaft 43 is fixedly installed on the top of the adjusting plate 41, an adjusting rod 44 is rotatably installed on the outer surface of the rotating shaft 43, a rotating wheel 45 is rotatably installed on the bottom of one end of the adjusting rod 44, the rotating wheel 45 is arranged on the top of the conveying roller group 11, a reset component 5 is installed on the other end of the adjusting rod 44, the rotating wheel 45 is used to squeeze one side of the plate material, and the other side of the plate material is attached to the outer surface of the conveying wheel 21, the reset component 5 provides an extrusion force for the adjusting rod 44 and the rotating wheel 45 to extrude the plate material, and resets the adjusting rod 44 after rotation.

[0038] By installing the support plate 4 on the other end of the conveying roller frame 1, the adjustment plate 41 can adjust the distance between the adjustment rod 44 and the plate through the moving component 42 according to the size of the plate, and adjust the adjustment plate 41 to a suitable distance. One side of the plate moves against the conveying wheel 21, and the other end of the plate presses against the adjustment rod 44, so that the adjustment rod 44 rotates an angle through the rotating shaft 43. The rotation angle of the adjustment rod 44 will pull the reset spring 502 of the reset component 5 to deform, so that the reset spring 502 pulls the adjustment rod 44 and the rotating wheel 45 at the bottom of the adjustment rod 44 to squeeze and adjust the other side of the plate, and the extruded plate is close to the outer surface of the conveying wheel 21. The angle of the plate is adjusted so that one side of the plate is attached to the conveying wheel 21 and the other side is squeezed by the rotating wheel 45, so that the conveying position of the plate is limited, so as to achieve the effect of accurately docking the plate to the inside of the edge banding machine for edge banding.

[0039] First, considering the different sizes of the plates, it is necessary to adjust the distance between the adjustment plate 41 and the plate to limit the extrusion of the plate. Figure 3-Figure 4 , the specific structure of the moving component 42 is disclosed. The moving component 42 includes a docking column 401 fixedly installed on the top of the support plate 4 and a slide groove 402 opened on the top of the adjustment plate 41. The docking column 401 is clamped in the inside of the slide groove 402, and the adjustment plate 41 is clamped on the outside of the docking column 401 through the slide groove 402, and can be adjusted and moved on the top of the support plate 4. The internal thread of the docking column 401 is connected with a fastening bolt 403, and the bottom of the fastening bolt 403 is against the top of the adjustment plate 41 to fix and limit the adjustment plate 41 after the movement position.

[0040] A connecting column is fixedly installed on the top of the support plate 4, so that the adjustment plate 41 can be clamped to the outside of the connecting column through the slide groove 402, and the adjustment plate 41 is pulled to move the adjustment plate 41 outside the connecting column with the help of the slide groove 402, so as to adjust the position of the adjustment plate 41, and the fastening bolt 403 is threadedly connected to the inside of the docking column 401, so that the fastening bolt 403 tightens and fixes the adjustment plate 41, thereby achieving the effect of adjusting the position of the adjustment plate 41.

[0041] Again, considering the problem of how the reset assembly 5 pulls and resets the adjustment rod 44, Figure 4 , the specific structure of the reset component 5 is disclosed. The reset component 5 is fixedly mounted on a connecting column 1 501 on the top of the support plate 4. A reset spring 502 is provided on the outer surface of the connecting column 1 501. The other end of the reset spring 502 is connected to a connecting column 2 503. The connecting column 2 503 is fixedly mounted on the top of the adjusting rod 44. The adjusting rod 44 rotates to pull the reset spring 502 to deform, so that the reset spring 502 provides a pulling force to the adjusting rod 44.

[0042] An auxiliary rod 6 is sleeved on the outer surface of the second connecting column 503. A second rotating wheel 61 is rotatably installed at the bottom of one end of the auxiliary rod 6 away from the second connecting column 503. The second rotating wheel 61 is used to assist the first rotating wheel 45 to extrude and transport the plate.

[0043] By installing a second connecting column 503 on the top of one end of the adjusting rod 44, one end of the return spring 502 is connected to the second connecting column 503, and the other end is connected to the first connecting column 501 on the top of the supporting column. The adjusting rod 44 is set to be "L" shaped. When the plate squeezes the rotating wheel 1 45 at the longer end of the adjusting rod 44, the adjusting rod 44 rotates through the rotating shaft 43, so that the shorter end of the adjusting rod 44 pulls the return spring 502 to squeeze the side of the plate, so that the plate is squeezed and accurately docked into the edge banding machine. When not conveying, the side of the adjusting rod 44 is supported by the blocking column, so that the adjusting rod 44 will not be pulled by the return spring 502 to deviate the angle.

[0044] Secondly, the outer surface of the connecting column 2 503 is sleeved with the auxiliary rod 6, and the angle between the auxiliary rod 6 and the adjusting rod 44 is adjusted to a suitable angle, so that when the adjusting rod 44 rotates the angle and the rotating wheel 1 45 contacts the side of the plate for extrusion, the auxiliary rod 6 rotates the angle together with the adjusting rod 44, so that the rotating wheel 2 61 also contacts the side of the plate, and the auxiliary rotating wheel 1 45 extrude and convey the side of the plate, thereby adjusting the conveying position of the plate.

[0045] Finally, considering that when the conveyor roller group 11 conveys the plate, the plate will fluctuate on the conveyor roller group 11, resulting in inaccurate plate docking, Figure 5-Figure 8 The specific structure of the pressing component 3 is disclosed. The pressing component 3 includes a fixed plate 31 fixedly installed on the top of the fixed frame 2, a movable plate 32 is fixedly installed on the outer side of the fixed plate 31, three connecting plates 33 are fixedly installed on the bottom of the movable plate 32, and two groups of pressing wheels 34 are rotatably installed in the middle of the three connecting plates 33. The pressing wheels 34 are set on the top of the conveying roller group 11 to press and convey the top of the plate.

[0046] A vertical plate 301 is fixedly installed on one side of the movable plate 32 close to the fixed plate 31, a hole is opened on the outer side of the vertical plate 301, a sliding groove 302 is opened on the outer side of the fixed plate 31, a fastening bolt 303 is slidably installed inside the sliding groove 302, the fastening bolt 303 penetrates the sliding groove 302 and the hole and extends to the outside of the vertical plate 301, a fastening cap 304 is sleeved on one end of the fastening bolt 303 close to the vertical plate 301, so that the vertical plate 301 can be adjusted on the fixed plate 31 with the help of the fastening bolt 303, and the distance between the pressing wheel 34 and the conveying roller group 11 is adjusted.

[0047] By fixing the fixed plate 31 on the top of the fixed frame 2 and fixing the vertical plate 301 on the top of the movable plate 32, the vertical plate 301 can be fitted on the side of the fixed plate 31, and a sliding groove 302 is opened on the side of the fixed plate 31, so that the fastening bolt 303 passes through the sliding groove 302 and the hole opened on the vertical plate 301, and a fastening cap 304 is threadedly sleeved on one end of the fastening bolt, so that the vertical plate 301 and the movable plate 32 are fixedly installed on the side of the fixed plate 31, and the movable plate 32 can adjust its height in the sliding groove 302 on the fixed plate 31, and adjust the movable plate 32 to a height that matches the thickness of the plate, so that when the plate passes through the pressing wheel 34 at the bottom of the movable plate 32, the pressing wheel 34 can press the top of the plate to avoid the plate from fluctuating, resulting in the problem that the plate cannot be accurately docked into the edge banding machine.

[0048] In summary, the working principle of this solution is as follows:

[0049] When edge banding the plate, the staff or the mechanical arm place the plate on the conveying roller group 11 in turn, the driving component 12 is controlled by the controller, and the conveying roller group 11 is powered to convey the plate on the top of the conveying roller group 11, and the tapered roller on the conveying roller group 11 can convey the plate to the side close to the conveying wheel 21 for conveying. When the plate is conveyed to the conveying wheel 21, the conveying wheel 21 cleans the side of the plate and limits the conveying of one side of the plate. At this time, the head end of the other side of the plate impacts the adjusting rod 44, so that the adjusting rod 44 rotates an angle through the rotating shaft 43. When the adjusting rod 44 rotates an angle When the plate passes through, the plate continues to be transported forward, and the adjusting rod 44 and the rotating wheel 1 45 are pulled by the reset spring 502 to squeeze the side of the plate. At the same time, the auxiliary rod 6 is also pulled by the reset spring 502, so that the rotating wheel 1 45 and the rotating wheel 2 61 squeeze the side of the plate for transportation. The rotating wheel 1 45 and the rotating wheel 2 61 follow the plate and rotate on the side of the plate. No resistance is formed to the transportation of the plate, so that one end of the plate is attached to the conveying wheel 21 for transportation, and the other end is squeezed by the rotating wheel 1 45 and the rotating wheel 2 61, so that the conveying position of the plate is limited, and it can be accurately connected to the edge banding machine connected to the conveying roller frame 1.

[0050] When the two sides of the plate are limited by the conveying rollers and the rotating wheel 45, the pressing wheel 34 is at the top of the plate to press the top of the plate, so as to achieve the effect of all-round limited conveying of the plate, and the plate can be accurately docked to the inside of the edge banding machine for edge banding.
